I wanna join all the field as a new col.
but how can i ignore the empty field because i always join the field and separate by space like the following.
select (field_1+' '+field_2+' '+field_3) as new_col from TABLEA
but if the field is empty, then there is the double space
how can i ensure all the space is one space only.
I have a gridview with two textboxes (first name & last name) and a linkbutton to search results inside the gridview.
I have made select parameters as well and the search works if i write in both textboxes. However, if I leave one textbox blank, i don't get any results.

How can I get results from searching only one textbox?

I have a aspx page with a ascx control inside an ascx control and the required field validator is not hit on the action of the page.
The issue is with the 2nd nested ascx control. The field validators in the first ascx control validate correctly, but with the ascx control inside the ascx control there are issues.
The nested ascx control is a repeater control and this may be the reason, but I am unsure.
I'm not exactly sure what question to ask, but I'll list a few below.
How do I attach the field validators up a level to the 1st ascx control?
Is it possible to put required fields into a nested ascx control?
I have a 20 to 30 fields on a form. Most of them are optional. However, the users can fill out what they want. If a user dosen't fill in a field when data is sent to the database it's sent as blank, instead of NULL. Is there a way I can generically say "for all textboxes if Equals("") then DBNull.Value". Without going through each and every textbox?

I have a 2D array of doubles in my Default class on my Default.aspx.cs page, like so:
protected Double[,] time;
By the time the page loads, I have populated this array from a database. Now, I want to reference this array in another file (Diff.aspx.cs) to avoid visiting the database again. Also, the data is used in a read-only fashion.
I have a detailsview on my page binding a table with information about the employees. They can update their information. Some info should be visible but not updateable. I could change the update command not updating but I like the control where I can set the column to read only. In that way the employee will find the data visible and they will see that the field/column cannot be changed. But having the column read only will return a null-value into that column when editing and updating anything. Why is that? Shouldn't it just update it's read only value?

I have 2 fields in my gridview one called ScriptType the other BagNo, when a user click the edit button, I would like the BagNo filed to be disabled if the ScriptType field is = "TTA" and enabled otherwise. How can I do this?..something along these lines see below..I am using VB..

I have a DetailsView on the page and I have made one of the fields a TemplateField. In the EditItemTemplate and InsertItemTemplate I have a DropdownList that is databound to a table in my Sql Server database. I wanted to add an initial value to the DropdownList
namely "- select -" .
I set the AppendDataBoundItems property to true and added the initial value as a ListItem.Markup of the DropdownList
<asp:DropDownList ID="DropDownList_HP" runat="server"
AppendDataBoundItems="True" DataSourceID="SqlDataSource_HP" [code]...
This works fine for new input. The problem is however that the database already has records that were entered through a Windows Application and many of these records has a null value in this field and exceptions are thrown when I tried to open these records
and the system tried to set the SelectedValue of the DropdownList.After some more searching I found this help
http://msdn.microsoft.com/en-us/library/ms366709.aspx
So I changed the ListItem in the DropDownList markup to the following:
<asp:DropDownList ID="DropDownList_RefHospDV4" runat="server"
AppendDataBoundItems="True" DataSourceID="SqlDataSource_RefHosp" [code]...
This now solved the problem of opening a record where the value is null in the database, BUT now the RequiredFieldValidator is not validating anymore to make sure that a databound item is selected for this field and not the initial value "- select -". So basically now it is not checking anymore to see if valid input has been entered for the DropDownList and it accepts "- select -" thus it acts as if the field is not a required field anymore.
In short what is required is that I want to make sure that the user enters a valid selection in the DropDownList, but it must also cater for old records that do not have this field entered yet so that those old records can be opened in the DetailsView .Opening Old records (with null in that field):When these old records are opened in the DetailsView the DropDownlist should show "- select -" when the value in the database is null.
Saving records (old or new records):When saving the record in Insert mode or Update mode the RequiredFieldValidator should show that a valid input is not selected if the DropDownList is still on "- select -".
I'm using Entity Framework for my object-relational mapping, and jqGrid for my grid.
I have an Employee entity, that contains a ContactID field. I have a Contact entity that contains fields FirstName and LastName.
I want to display a list of Employees in a grid, and give the user the ability to sort by FirstName and LastName.
Here's what I have right now:
public JsonResult GridData(string sidx, string sord, int page, int rows)
{
var pageIndex = Convert.ToInt32(page) - 1;
var pageSize = rows;
var totalRecords = GetAllEmployees().Count();
var totalPages = (int)Math.Ceiling(totalRecords / (float)pageSize);
IQueryable<Employee> employees = GetAllEmployees().
OrderBy(sidx + " " + sord).
Skip(pageIndex * pageSize).
Take(pageSize).ToArray();
}
As you can see, this only gives me the ability to sort by fields in the Employee entity, so I can't sort by FirstName and LastName.
How can I modify this to accomplish that?
is both same
